Question

for each scenario listed on the left, determine whether the scenario represents an independent samples or matched pairs (dependent samples) situation by placing the appropriate letter in the box provided. comparing pain levels of a group receiving a placebo to a group receiving a medicine comparing pain levels before and after treatment with magnetic therapy comparing pre - test scores with post - test scores after summer training camp comparing the number of speeding tickets received by men to the number received by women a. independent samples b. matched pairs (dependent samples)

Explanation:

1. Comparing pain levels of a placebo - group and a medicine - group: The two groups are different and not related in a paired - way, so it's independent samples.
2. Comparing pain levels before and after magnetic therapy: The same subjects are measured at two different times, so it's matched pairs.
3. Comparing pre - test and post - test scores after summer training camp: The same individuals are measured before and after, so it's matched pairs.
4. Comparing the number of speeding tickets of men and women: The two groups (men and women) are different and not paired, so it's independent samples.

Answer:

1. a. Independent Samples
2. b. Matched Pairs (Dependent Samples)
3. b. Matched Pairs (Dependent Samples)
4. a. Independent Samples
